JI VG100 Project1:Naval Battle Robot

We are freshmen in Joint Institute in Shanghai Jiaotong University which is located in Minhang District of Shanghai. In JI we are supposed to develop an ability of solving problems as a real engineers and also an ability of teamwork. Our team is called R.E. The letter “R” represents the robot we design and “E” represents engineering. Also it is an abbreviation of “rennen” which in German means running.

In VG100, we are required to design and construct a robot so that it can move balls from our field to our opponents’ field. The competition is called “Naval Battle” and the balls are considered to be our canons. With a limit of 3 minutes we can get scores by counting the canons in opponents’ territory at the end of the battle.

Basic regulations of the robot:

-Field: An 2000mm*1500mm rectangular area

From the bottom of the wall in the middle to the ground: a gap of 50mm

-The wall: 70mm in height and 18mm in width

-Pingpong balls*8: diameter of 40mm

-Wooden balls*4: diameter of 70mm

Rules of the game:

Time limit: 3 minutes

• Dimension limit for robots:350mm*350mm*200mm

• Only the motors provided are eligible

• Players are allowed to move opponent’s ball back to the opponent’s territory

• The score will be counted at the end of the game

• The ranking will be determined by the following order:

1.Total score

2. The number of the large balls on the opposite side

• If two teams are of the same ranking, an additional 1-minute match between these two teams will be held.

Two rounds are included:

Individual round:

Move all the ball into enemy's territory individually without an enemy

8 Teams who use the shortest time enter the knock out and fight for a champion

Step 1: Concept Diagram

Shovel: 1.To push the small balls into the enemy’s territory

2.To lift the big balls and pour into the enemy’s territory

Pulley2 and 3: To control the height of the shovel by wires

Pulley 1: To control the opening direction of the shovel

Mechanical arms: To lift up or lay down the shovel

Wooden rod: To keep a balance between two edges of the shovel so that the ball won’t creep down from the
